Loss-in-weight system controller S52c

Overview
The S52c weigh-belt and Loss-In-Weight controller provides straightforward setup, calibration and maintenance via an intuitive menu. Built-in software checks reduce operator error and simplify commissioning.

Function
The S52c controls and monitors material flow on weigh-belt and Loss-In-Weight feeder systems by measuring load and speed. Weight is processed as mass per length and speed as length per time to deliver continuous control of target flow rates or set-points. In Loss-In-Weight mode the controller calculates instantaneous flow and cumulative totals from feeder weight change. Speed input supports volumetric control, refill logic and disturbance compensation. Operational data is displayed locally and can be communicated over fieldbus.
